Root canal treatment (also called endodontics) is a procedure to remove the nerve from a tooth, clean the root canals and fill them. This helps to retain the tooth in its natural form.
The nerve which is in the root of the tooth can become inflamed, painful or infected if decay progresses deep into the tooth or if a tooth is heavily filled. In order to save the tooth and stop the infection from spreading to the surrounding tissues, the diseased pulp needs to be carefully removed, the root canal system needs to be cleaned, shaped and sealed to prevent bacterial contamination. It is a delicate, time consuming procedure. It restores the tooth, allows function and avoids extraction.
